Additional details on cost and reservations will be included in the next newsletter. BOTTLE GENTIANS by Dr. James S. Pringle Part II of II One naturalist told his readers that one could tell whether or not bottle gentian flowers had been visited by bees, because as the bee left a flower, it pushed the fringed portions of the corolla summit out where they could be seen; until the flowers had been pollinated, he said these fringes were concealed. Actually, this naturalist must have observed two species of bottle gentian. The minutely fringed corolla summit is characteristic of G. andrewsii, even in the early stages of development before the flowers become attractive to bees; a smooth, rounded corolla summit without exposed fringes distinguishes G. clausa from its better-known relative. Gentiana andrewsii, which is sometimes distinguished as the prairie closed gentian or finger-tip closed gentian, is found in the interior or North America, whereas G. clausa, the meadow closed gentian, is restricted to the eastern part of the continent. Gentiana andrewsii is frequently reported outside its actual range, because the bizarre flowers readily attract the attention of beginners, who learn "closed or bottle gentian, Gentiana andrewsii" almost as soon as they learn that plants have scientific names. There are, however, other gentians with equally tightly and permanently closed corollas. In addition to G clausa, there is G. austromontana, the Roan Mountain or Blue Ridge gentian, a companion of the Catawba rhododendron in the high-altitude "balds" of the southern Appalachians — a species of conservation concern because of its limited range and the vulnerability of its habitat. Several other species have corollas nearly as completely closed, including G. saponaria, the soapwort gentian, which is widespread in the southeastern United States, in swamps and wet or dry woodland openings; G. villosa, the striped gentian, a less common species in the southeastern United States, usually in dry woods; G. linear is, the narrowleaved or bog gentian, in bogs in eastern Canada and the northeastern United States; G. rubricaulis, the red-stemmed or Great Lakes gentian, in fens and similar calcareous wetlands from the Great Lakes region north to James Bay; and G. alba, the yellowish or pale gentian, in the tall grass prairies. Those familiar with the principle of priority in botanical nomenclature may find it interesting that, although G. andrewsii is the name that is widely misapplied, all of these species except G. austromontana were given their scientific names before G. andrewsii. Typically, the corollas of G. andrewsii are deep blue, with white tips on the fringes at the summit. In Ontario, plants with white corollas, called forma albiflora, are most frequently encountered. Usually only one of these colour-forms occurs at any one locality. The much rarer forma rhodantha has pinkish-violet corollas. Similar variation occurs in the soapwort and bog gentians, and in several of the other species that usually have blue corollas. As some of the names indicate, however, not all gentian species normally have blue corollas. The corollas of G. villosa are pale green, often with some purplish suffusion on the lobes, and those of G. alba are white or faintly yellowish. Gentiana mirandae, a Mexican species, has tubular scarlet corollas, open at the summit, that doubtless attract hummingbirds. The North American species of Gentiana are remarkable in the extent to which diversity in floral form has evolved unaccompanied by the development of genetic barriers to interspecific hybridization. Nevertheless, although the species with closed or nearly closed corollas are interfertile, hybridization among them is uncommon, because each species is restricted to a different habitat or geographic region. For example, in the Lake Superior region, G. linearis is associated with acid bogs and the strongly acid soils of the Canadian Shield, whereas the closely related G. rubricaulis grows in calcareous fens and soils formed from limestone and basic intrusive rocks. Likewise, where the rages of G. andrewsii and G. clausa overlap in northeast Ohio, G. andrewsii grows where the soils are nearly neutral and high in calcium, derived from the limestones of the Interior Low Plateaus, and G. clausa grows where the soils are acid and low in calcium, derived from the granites and similar rocks of the Appalachians.

The University of British Columbia Vancouver, Canada http://www.library.ubc.ca/spcoll/thesauth.html ABSTRACT Dioecy, the breeding system with male and female function on separate individuals, may affect the ability of a lineage to avoid extinction or speciate. Dioecy is a rare breeding system among the angiosperms (approximately 6% of all flowering plants) while hermaphroditism (having male and female function present within each flower) is predominant. Dioecious angiosperms may be rare because the transitions to dioecy have been recent or because dioecious angiosperms experience decreased diversification rates (speciation minus extinction) compared to plants with other breeding systems.
